IV. DEVICE DESCRIPTION
HipCheck enables the surgeon to intraoperatively measure alpha angle during hip arthroscopy procedures for femoroacetabular impingement. The software is provided to the user pre-installed on a mobile touchscreen tablet for which it has been tested for compatibility.
Alpha angle is a value used to indicate cam deformity of the femoral head, seen in patients presenting with femoroacetabular impingement. HipCheck provides a visualization tool for surgeons to determine the alpha angle intraoperatively, using virtual measurement tools superimposed on X-ray images collected during the procedure, which informs clinical decision making.

on the Femoral Head Detector algorithm used in the FluoroMap 1.0 software, which
belongs to the secondary predicate device, the FluoroMap Computer Assisted Surgery
System (K103400).
V. INTENDED USE
HipCheck provides static localization information derived from image processing of intra-
operatively acquired X-ray images, by superposition of virtual measurement tools onto
those X-ray images.

Discussion of Similarities and Differences
Primary Predicate (Dyonics Plan, K132636): Dyonics Plan is a surgical planning tool, in that
its operational environment is primarily pre-operative, thereby outside the surgical suite.
However, the software allows for the export of the plan in PDF or HTML format, which can
be referenced intraoperatively. As such, the Dyonics Plan utilizes CT preoperative imaging
for displaying 2D views and 3D renderings and provides virtual measurement tools for
visualization and analysis of hip preservation treatment options. HipCheck’s operational
environment is primarily intraoperative, within the surgical suite. Since HipCheck is
primarily used intraoperatively, it displays intraoperatively collected X-ray images,
likewise providing virtual measurement tools for visualization purposes during
femoroacetabular impingement procedures.
While the operational environment may differ, the intended use is the same. Dyonics Plan
utilizes image processing of preoperative CT images and virtual measurement tools to
visualize hip anatomy and plan preservation procedures. HipCheck utilizes image
processing of intraoperatively collected X-ray images and virtual measurement tools to
visualize hip anatomy during femoroacetabular impingement procedures. The Dyonics Plan
and HipCheck have the same intended use, as defined in their shared regulation 21 CFR
892.2050. Though their indications for use statements differ, both are used in the
treatment of femoroacetabular impingement.
Secondary Predicate (FluoroMap, K103400): In addition to its clearance as an orthopedic
stereotaxic instrument (OLO; 21 CFR 882.4560), FluoroMap is also cleared as a picture
archiving and communications system (LLZ; 21 CFR 892.2050). This is due to the core
functionality of FluoroMap’s software that supports the acceptance, display, and digital
processing of X-ray images in order for FluoroMap to function as intended. FluoroMap
software facilitates image manipulation and quantification in order to achieve visualization
of the placement of virtual implants and instruments.
Similarly, HipCheck shares this core functionality to achieve visualization of the placement
of virtual measurement tools for the determination of alpha angle. HipCheck’s Alpha Angle
algorithm is built directly on the Femoral Head Detector algorithm within the FluoroMap
software (K103400). HipCheck leverages the Femoral Head Detector algorithm from
FluoroMap for its same intended purpose, simply in a different application.
While the primary function of FluoroMap is as a navigated surgical system for placing
orthopedic implants, the how behind the device’s ability to achieve its intended purpose is
important in the substantial equivalence discussion for HipCheck.

VIII. PERFRMANCE DATA/NON-CLINICAL TESTING
Design verification testing was performed on HipCheck as a result of the risk analysis and
product requirements. Testing included software and bench verification testing, as well as
design validation. Design validation testing was conducted in a simulated-use environment
by surgeon and nurse users. Users were successfully able to use the HipCheck as intended
to determine the alpha angle and utilize the virtual measurement and visualization tools.
Software testing
Software testing was conducted and documentation was provided as recommended by
FDA’s Guidance for Industry and FDA Staff, “Guidance for the Content of Premarket
Submissions for Software Contained in Medical Devices.” The software for this device was considered to be of “moderate” level of concern since a failure or latent flaw in the software
could indirectly result in minor injury to the patient or operator.
Alpha Angle Performance Testing
Alpha angle performance was evaluated in both verification and validation testing
performed for HipCheck. Verification testing was conducted based on the identified design
requirements and software requirement specifications of the Alpha Angle Core Algorithm.
Additionally, validation testing was conducted to ensure applicable user needs were met
for generating, manipulating, and using the overlay to determine the alpha angle. All testing
had overall passing results.
Mechanical testing
Mechanical functionality testing included the following to ensure the device design meets
user needs in the environment of use:
- Battery life
- Tablet weight
- Tablet securement and attachment force to evaluate the connection between the
tablet and its docking interface on the compatible operating table mounting arm
- User interface temperature and functionality at operating temperatures
- RF ablation interference
- Mounting arm staying force
- Simulated-use testing
Electrical safety and electromagnetic compatibility (EMC)
Electrical safety and EMC testing was conducted on the compatible touchscreen tablet that
the HipCheck software is provided pre-installed on. The tablet complies with the IEC
60601-1 standard for safety and the IEC 60601-1-2 standard for EMC.

Animal Study
No animal testing was conducted to determine the safety and effectiveness of HipCheck.
Clinical Studies
No human clinical testing was conducted to determine the safety and effectiveness of
HipCheck.
IX. CONCLUSIONS
Based on the shared technological characteristics and intended use, HipCheck is
substantially equivalent to the primary predicate, Dyonics Plan Hip Impingement Planning Software (K132636), and the secondary predicate, FluoroMap Computer Assisted Surgery
System (K103400). Differences between the subject and predicate devices’ technological
characteristics do not raise different questions of safety and effectiveness of HipCheck. The
results of the non-clinical testing conducted supports the safety of the device and
demonstrates that HipCheck performs as intended in the specified use conditions.
